Title: WRAP RMC An Improved Ammonia Inventory for the WRAP Domain


1
WRAP RMC An Improved Ammonia Inventory for the
WRAP Domain
  • ENVIRON International Corporation
  • and
  • University of California, Riverside
  • August 27, 2004

2
Objectives
  • Improved 2002 NH3 emission inventory for WRAP
  • Consider major source categories
  • Improved temporal/spatial allocation
  • Incorporate environmental factors
  • Develop GIS-based modeling system

3
Source Categories
  • Livestock
  • dairy beef cows, poultry, swine, sheep, horses
  • Fertilizer Usage
  • Native Soils
  • urban, barren, forest, shrub/grassland, wetlands
  • Domestic
  • Respiration, perspiration, infant diapers, cats,
    dogs
  • Wild Animals
  • Grizzly bears, Black bears, Elk, Deer

4
Emission Factors
  • Livestock
  • Battye, et al, 2003 Chinkin et al., 2003
  • Fertilizer application
  • EEA, 2002 Potter et al., 2001
  • Native Soils
  • Battye et al., 2003 Chinkin et al., 2003 Potter
    et al., 2001
  • Domestic sources
  • Chitjian et al., 2000
  • Wild Animals
  • CMU Model (Strader et al., 2004)

5
Activity Data
  • Livestock headcounts National Ag Services
    Statistics (NASS, 2003)
  • Fertilized usage Assoc. of American Plant Food
    Control Officers (AAPFCO, 2003) USDA NASS
  • Native soils Land cover acreage (NLCD)
  • Domestic 2000 US Census Pet per capita ratios
    from Dickson et al., 1991
  • Wild Animals CMU NH3 model

6
Temporal Allocation
  • Livestock
  • Monthly profiles recommended by Chinkin et al.
    (2003)
  • Diurnal profiles based on Russell Cass (1986)
  • Ei ? 2.36(Ti-273)/10 ViA
  • Fertilizers
  • Monthly variation from fertilizer usage data
  • Diurnal profiles based on Russell Cass (1986)

7
Temporal Allocation
  • Native Soils
  • Temporal variation based on environmental
    parameters
  • EFadj EF (1-M)1/110(0.092730/T-cpH)
  • Domestic Wild Animal Sources
  • Temporally invariant

8
Spatial Allocation by Source Category
9
Landuse, Population Environmental Data
  • Land Use/Land Cover (LULC)
  • NLCD LU/LC coverages -- GIS rastor data high
    spatial resolution (30 m) 21 LU/LC
    classifications for land use
  • Population
  • 2000 US Census data assembled by EPA
  • Soil pH
  • STATSGO
  • Soil Moisture, temperatures, wind speeds
  • 2002 36-km MM5 modeling results

Summary
  • 2002 NH3 emission inventory for WRAP
  • Livestock, fertilizers, soils, domestic sources,
    wild animals
  • Updated emission factors, temporal allocation
  • Incorporates environmental parameters
  • Temperature soil moisture, pH wind speed
  • GIS-based NH3 emissions modeling system
  • Draft 2002 inventory complete
  • Compares favorably w/ CMU model for most
    categories
